PATENT HENRY A. FRYSLIE, OF CICERO, ILLINOIS.

HEATlNG AND VENTILATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 533,454, dated February 5, I895. Application filed March 16, 1893. Serial No. 466,226- (No model.)

To all whom it 12mg concern:

Be it known that I, HENRY A. Fnvsmaa citizen of the United States, residing at Cicero township, in thecounty of Cook and State of Illinois, have invented certain new und useful Improvements in Heating andVentilating Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled 1n the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to heating and ventilating devices, and consists in the use of an outer casing for a chimney for the purpose of forming an intermediate chamber for the circulation of air whereby the heat ordinarily escaping through a chimney due is utilized both for the purpose of warming a house and setting up a circulation for the purpose of ventilation; ventilating flues being provided in the walls of the house and communicating with the upper portion of the ventilating chamber.

In the accompanying drawings 1 show at Figure 1 a vertical, longitudinal section of a dwelling house, provided with my improved heating and ventilating device. Fig. 2 is a plan section on the line 2, 2, of Fig. 1. Fig. 3 is an elevation of the cap of the ventilating chamber. Fig. 4c is a plan section on the line 4., 4, of Fig. 3. Fig. 5 shows details of the damper across the air chamber; and Fig. 6 is a transverse section of the casing E, on the line 6, 6, of Fig. l.

I represent at A, B, lower and upper rooms, respectively, of a dwelling house, and at G, the attic, the roof of the building being shown at o.

D, is the smoking flue, closed at the bottom and extending upwardly through the roof of the house and having its upper end open and covered by a conical cap d, supported by braces d.

An outer casing E, incloses the smoke flue, a chamber or flue being left between the walls of the smoke flue and the casing E. The casing E, is open at the lower end and has a transverse partition thrown across its chamber as indicated atE. This partition may have perforations 7t, and'he provided with a damper K, which as shown is in the form of a ring resting between upwardly projecting guide flanges m, and being provided with openings 70, adapted to register with the openings in, and a handle K, projecting through the side of the casing E. This casing E, extends through the roof and terminates below the top of the smoke fine, its upper end-being covered by a cap F, which is provided with a series of openings f, f, so situated as to be protected from the weather. Registers h, h, of ordinary construction are provided in the casing E, so as to communicate with the rooms A, B, these registers being preferably located near the ceilings of the rooms. Similar registers e, e, are also placed in the casing E, near the floors of the rooms.

I show at G, an ordinary heating stove, and g, 9, represent stove-pipes which communicate with the smoke flue D.

A ventilating flue H, is built into the wall of the house and opens to the rooms by means of the registers h, it, near their floors, 72. 72. near their ceilings and communicates with the chamber of the casing E, in the attic.

At I, is shown a portion of a line leading from a part of the house not shown, and being connected with the flue I-I.

Two ventilating registers are placed in each room as shown, the lower ones for use in cold Weather, and the upper ones for use in warm weather.

The action of the device is as follows: The hot smoke in the flue D, warms the air in the chamber of the casing E, and causes its upward movement. The partition E, prevents it from finding its way out at the top of the stack and it is consequently discharged through the registers h, 72., into the rooms of the dwelling, the registers e, c, being closed. The upper end of the smoke flue sets up a circulation through the ventilating flues H, I, and draws the air out of the rooms, its circulation being facilitated by the discharge of air through the registers 72., h. The lower end of the chamber of the casing E, may open to the basement of the house or may be supplied. :00

with air by a duct from without if desired. The use of the air duct is common in furnaces and I have not deemed it necessary to show it in the drawings. In the summer time this system of flueswill tend to cool the house, the lower ventilating registers h, h, the registers h, h, and the damper K being then closed and the warm air drawn from the rooms through the registers h The upper movement of the air through the ventilating fines will tend to draw the air into the rooms through the registers e, e, even though there may be no heat in the flue D.

If the flue D, is in use, and consequently hot, the house is more effectively ventilated by closing the damper L, and opening the damper K. The registers h, h, or e, 2, may be used as desired and the circulation will be from the rooms through the chamber of the casing E.

This device will be quite as effective in houses heated by furnaces located in the basement as in those heated by stoves after the manner shown in the drawings.

I claim- 1. The combination with a chimney of an outer, casing inclosing and forming an air chamber around the chimney, the chamber beiug open at its upper and lower ends and having lateral openings communicating with the rooms of the house, a transverse partition across the air chamber above the highest lateral opening and ventilating fines leading from the rooms to the air chamber and entering it above the transverse partition, substantially as described and for the purpose specifled.

2. The combination with a chimney of an outer casing for inclosing and adapted to form an air chamber about the chimney, a damper or valve for closing the bottom of the air chamber a valved partition across the air chamber near its upper end, and registers for opening the air chamber to the rooms of the house, the whole being so arranged that fresh air may be drawn through the air chamber anddelivered into the house, or air may be drawn from the house through the air chamber and discharged above the roof, substan tially as describedand for the purpose specified.

3. The combination with a chimney,a casing for inclosing and forming an air chamber about the chimney, and a transverse partition across the upper part of the air chamber, of registers opening the air chamber to the rooms of the house,ventilating fiues leading from the rooms and communicating with the air chamber above its transverse partition, whereby the heat of the chimney may be utilized for conveying fresh air to the house and drawing foul air therefrom, substantially as described HENRY A. FRYSLIE.
